APPARATUS FOR AUTOMATED DETERMINATION OF A LUMEN CONTOUR OF A BLOOD VESSEL |
(57) In part, the invention relates to a method for sizing a stent for placement in a
vessel. In one embodiment, the method includes the steps of: dividing the vessel into
a plurality of segments, each segment being defined as the space between branches
of the vessel; selecting a starting point that appears to have substantially no disease;
defining the diameter at this point to be the maximum diameter; calculating the maximal
diameter of the next adjacent segment according to a power law; measuring the actual
diameter of the next adjacent segment; selecting either the calculated maximum diameter
or the measured maximum diameter depending upon which diameter is larger; using the
selected maximum diameter to find the maximum diameter of this next segment; iteratively
proceeding until the entire length of the vessel is examined; and selecting a stent
in response to the diameters of the end proximal and distal segments.
